Lucky 4CS Cartridge System


 Product Description

The new MXT Lucky System (Lucky) is the newest advancement for WP 4CS forks. The Lucky system is the result of innovative engineering and a commitment to bring riders the best value in the suspension market. Lucky Nichols, a professional suspension tuner, was discussing some long range fork projects with Jeremy Wilkey, and suggested that the existing MXT 4CS Asymmetrical kit could be “repackaged” with the new cartridges and hardware that MXT is currently producing. Springs included. Major enhancements include:

  • Over a pound lighter than stock 4CS forks
  • Increased cartridge volume to a 22mm diameter
  • A redesigned Huck Valve
  • New compression and rebound adjusters
  • Quality machining to reduce friction
  • DIY: Drop in ready system
  • Fits any WP 4CS fork

  1. Awesome Fork Cartridges 5 Star Review

    Posted by on May 28th 2019

    I'm very impressed with the Lucky Cartridges system on my 2016 KTM 350 EXC-F Sixdays with WP 4CS forks. The system comes with new fork springs, spacers to setup the spring pre-load, good instructions for bleeding the forks. Easy installation. Does not include new fork bushings or fork seals. The staff at Lucky's are very helpful and their responses very quick.

    The forks are plush on the first 4-6 inches of travel and smooth but firm through the mid stroke. No more harsh bottoming out either. The forks do not deflect when riding rocky trails the forks just absorbs it up. The forks also perform great on squared edges holes and uphill deflections. These Lucky fork cartridges made a great improvement on my bike's suspension. I don't work as hard to control the direction of my bike.

    The only regret I have is I should of did the change sooner. I would recommend the Lucky Cartridge system for WP 4CS forks. It's a great improvement over the stock forks. Another advantage is the fork cartridges can be switched to another bike if you sell your bike.
